CVE-2016-2342: n/a vulnerability

CVE-2016-2342: The bgp_nlri_parse_vpnv4 function in bgp_mplsvpn.c in the VPNv4 NLRI parser in bgpd in Quagga before 1.0.20...

The bgp_nlri_parse_vpnv4 function in bgp_mplsvpn.c in the VPNv4 NLRI parser in bgpd in Quagga before 1.0.20160309, when a certain VPNv4 configuration is used, relies on a Labeled-VPN SAFI routes-data length field during a data copy, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted packet.

Security readout for executives and security teams

This flaw affects Quagga bgpd when VPNv4 routing is configured. A crafted BGP packet can trigger a stack buffer overflow, potentially crashing the routing process or enabling arbitrary code execution. Business risk is highest for networks still running old Quagga packages on systems that process VPNv4/MPLS VPN routes. Exposure is limited to Quagga bgpd deployments using the affected VPNv4/Labeled-VPN SAFI functionality. General systems without Quagga bgpd or without that routing configuration are not shown as affected by the provided sources. Treat this as high priority for legacy routing environments. A successful attack could disrupt routing or compromise a routing daemon, but urgency depends on whether Quagga bgpd with VPNv4 processing is still deployed. Mitigation focus: Upgrade Quagga using vendor security updates for the affected operating system.; Ensure Quagga is at or newer than the fixed 1.0.20160309 release line.; Disable VPNv4/MPLS VPN route handling if it is not operationally required..
